PADDLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 683,776, dated October 1, 1901. Application iiled March 2,1901. Serial No. 49,588. (No model.)

To LZZ whom t may concern.'

Be it known that I, HENRY S. KLINE, a citizen of the United States, and a resident of McKeesport, in the county of Allegheny and State of Pennsylvania, have invented a new and 'Improved Paddle-Wheel, of which the following is a full, clear, and exact description.

This invention relates to improvements in paddle-wheels for steamboat-s and the object is to provide a paddle-wheel of simple c onstruction that may be used at the stern or at the sides of a vessel and having simple and positive means for causing the paddles to assume a vertical position upon leaving the water, thus releasing the great weight of water which is usually carried upward by the ordinary fixed paddles, and therefore using the whole elfective power of the wheel in propellingthe vessel.

I will describe a paddle-wheel embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is an end elevation, partly in section, of a paddle-wheel embodying my invention; and Fig. 2 is a section on the line ce of Fig. 1.

The paddle-wheel comprises end frames, each consisting of a rim 1,connected by spokes 2 to a hub 3, mounted on the driving-shaft 4. This driving-shaft has bearings in a suitable frame, one portion of which is shown at 5. Mounted between the end frames of the wheel are the feather or swinging paddles 6. Each paddle has trunnions 7 at its ends, which project through blocks on the end frames, and.

on a trunnion projected atone end through the end frame is a crank-arm 8, the wrist-pin of which is provided with aroller 9, so as to reduce friction to a minimum. These trunnions, it will be noted, are located nearer to the top edge of the blades than the lower edge, so that the weight of the lower portion will cause said blades to move toand maintain a substantially vertical position, as indicated by dotted lines in Fig. 1, after leaving the water.

On the inner sides of the spokes 2, near the ends, are Wedge-shaped blocks 10, adapted to be engaged by wedge-shaped blocks 11 on the adjacent ends of the blades, as will be hereinafter described.

Attached to the frame portion 5 is a casing 12, the opposite side walls of which are curved outward, as indicated at 13, and these curved walls are provided with openings to receive deiiecting devices, here shown each as consisting of two curved sections 14 and 15. Each section 15 at its upper end has pins 16', which pass into arc slots 17, formed in the side walls of the openings in the opposite sides of the casing, and the lower ends of the sections 14 are connected to shafts 18, arranged in the lower portion of said openings. Arms 19 extend from the shafts 18, and pivoted to the inner ends of these arms 19 are links 20, while pivoted to the other ends of said links 2O are blocks 21, mounted to swing on pins or bearings 22 in the casing.

Pivotally connected to each block 21 is a tappet-nger 23, and the opposite blocks are connected together by a connecting-rod 24. This connecting-rod, as here shown, is atcached to the pivots connecting the links 2O with the blocks. Extended radially from the shaft 4, within the casing 22, are arms 25, and on the outer end of each arm is an outwardly-extended pin 26, upon which a roller 27 is mounted.

In operation, assuming the wheel to be turning in the direction of the arrow d, the paddles entering the water will be forced to engage their blocks 11 with the forward sides of the blocks 10, and they will be so held until they leave -the water. During the rotation of the wheel the arms 25, of course, will be rotated, so thata roller 27 will engage with the tappet-nger 23, (indicated at the right-hand side of Fig; 1,) rocking the block 21 to a substantially vertical position, as shown, and rocking the block 21 (shown at the left-hand side of Fig. 1) to an inclined position, as indicated, and this movement through the link 2O and the arm 19 will rock the shaft 18, causing the sections 14 and 15 to move outward from the casing into the line of movement of the wristpins of the crankarms, and as these wrist-pins or the rollers thereon engage with the section 14 of the dedecting or turning device the blade will be turned substan- IOO tially to a vertical position with its lower edge uppermost, and thus no water will be carried with it. After the blade shall have moved sufficiently upward to disengage its crank from the shifting device the blade will turn by gravity to its normal position. The rollers 27 on the arms 25 will be permitted to pass the tappet-finger 23 at the left-hand side of Fig. 1 by swinging it upward, as indicated by the dotted lines. Of course when the wheel is moving in a direction opposite that indicated by the arrow a the defiecting device 14 15 at the right-hand side of Fig. 1 will be forced outward while the opposite one is drawn inward, and it is obvious that these movements are wholly automatic, and when the wheel is moving in said opposite direction the blocks 11 will engage with the blocks' 10 at the opposite side from that first named. Having thus described my invention, I

claim as new and desire to secure by Letters Patentl. A paddlenlieel, comprising end frames, blades supported by and mounted to swing between said end frames, a fixed casing at the outer side of one of said endframes, deecting devices each consisting of two pivotally-connected sections mounted to move into and out of openings at the opposite sides of said casing, means carried by the wheel-shaft for causing said movements of the shifting devices, and cranks carried by the shafts for engaging with said deflecting devices, substantially as specified.

2. A paddle-wheel, comprising end frames, paddles supported by and mounted to swing between said end frames, cranks arranged on projected trunnions of said paddles, a casing arranged at one end of the wheel and having openings in its opposite sides, deflecting devices movable into and out of said openings, each defiecting device consisting of two pivotally-connected segmental sections adapted for engagement with the cranks, shafts on which the lower sections of the defieenng devices are mounted, arms extended from said shafts, blocks mounted to swing in the casing, link connections between said blocks and their adjacent arms, a connecting-bar connecting the two blocks, tappet fingers mounted to swing on the blocks, arms carried by the wheel-shaft, and projections on said arms for engaging with said tappet-fingers, substantially as specified.

3. A paddle-wheel, comprising end frames, paddles supported by vand mounted to swing between said end frames, crank-arms on projected trunnions of said paddles, a casing fixed at one end of the wheel and having openings in its opposite walls,a deecting device adapted for engagement with the crank-arms and located in each opening, each defiecting device consisting of two pivotally-connected segmental sections, the upper section having pins at its upper end for engaging in arc slots in the walls of the opening, the lower end of the lower section being connected to a shaft at the lower end of the opening, blocks mounted to swing in the casing, means carried by the wheel-shaft for swinging said blocks, a connection between the two blocks, and connections between the blocks and the adjacent shafts of the defiecting devices, substantially as specified.

et. A paddle-wheel, having swinging paddles, blocks on the end frames of the wheel, blocks on the ends of the paddles for engaging with said first-named blocks, and means for swinging the paddles to a substantially Vertical position upon leaving the water, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
